Install Hashcat in AMD and using only CPU power
#1
Question 
Hello everyone,
 
 
I got some issues installing hashcat in my new server. I’m trying to install hashcat V6.1.1 and follow instructions to install it, but after installation I got this error message when I try to run a "hashcat -b":

Code:
hashcat (v6.1.1) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

* Device #1: Outdated POCL OpenCL driver detected!

This OpenCL driver has been marked as likely to fail kernel compilation or to produce false negatives.
You can use --force to override this, but do not report related errors.

No devices found/left.

Stopped: Wed May  5 11:54:17 2021

 
Trying to force the command to avoid warnings, I got this:

Code:
Do not report hashcat issues encountered when using --force.

I installed OpenCL runtime, but still having the issue,  Is there an other procedure to install hashcat in a new AMD server? or I missing something ...?
Any advice will be welcome.

I share with you more information there

The following command "hashcat -I --force" return this:

The goal for me now is to install hashcat on this server and use only CPU for the moment (I’m waiting for the GPU).
